That's a cool project. I use ImHex myself but wasn't even aware of this.

Over the years there has been a silly amount of projects in this space, it is very hard to keep track of them all.

I did try to summarize the ones I know about in the feng project, see here, under "SIMILAR WORK":

Was there anything in particular you wanted to bring to my attention about the ImHex pattern language?

From a quick glance it looks similar indeed, with the same basic building blocks as feng (data types and structs), while they use a rust inspired format, and I use yaml format (however I also use the rust-inspired data type naming u8, u16, s16 and so on).

A major difference is that feng strives to be usable with minimal/no programming (a custom dsl was developed around this idea), while the ImHex pattern language does look rather classic programming focused data processing (like 010 templates but more pretty syntax)
